The butte is out in the San Rafael Grasslands in Arizona, shown with immense clouds in the sky. The stormy clouds were coming in from the right side. Our picnic lunch was eaten inside the car because of the impending storm--it was almost like a floor show, watching the fast changes in the sky as we ate. The rain started as we drove away.
In the 30 minutes or so I spent in the San Rafael Grasslands, it went from blue skies with puffy white clouds, to being completely covered over in threatening clouds, and then rain. This shot shows the rainstorm coming in fast.
